Title: Automatic pneumatic projectile launcher
Inventor: HAUG THOMAS J DI
IPC: F28G1/12
Filed: 1998-10-30
Abstract: An automatic pneumatic projectile launcher (10) for automatically launching compressible cleaning projectiles (22) into a hose, pipe or tube is disclosed. The launcher (10) comprises a moveable hopper (12) having an opening (14) provided at a lower end thereof coupled to a feed tube (16). The hopper (12) is moved up and down vertically in a reciprocating motion by four double acting pneumatic rams (25), located adjacent each corner of the hopper (12). The feed tube (16) acts as a magazine for the projectiles (22), is stationary and is slidably received through the hopper base plate (18) so that it projects upwards into the hopper during a downward stroke. The shape of the feed tube (16) is selected so that projectiles (22) enter the mouth of the tube in a predetermined orientation one above the other. A self-loading mechanism (26) is operatively coupled to the feed tube (16) for loading a projectile (22) received therefrom into an air chamber (28). When a source of compressed air is connected to the air chamber (28) the projectile is launched into the hose, pipe or tube. The launcher (10) removes the need for manual loading and firing of projectiles and therefore eliminates operator fatigue.

Title: Furnace for obtaining and moulding of alloys
Inventor: KRUMIN JURIJ K
IPC: F27B3/00
Filed: 1988-06-17
Abstract: The oven is applied in the obtaining of alluminum by using electrical or gas ovens with an inductor using an elusive magnet field. The construction allows to divide the mixing and alloy spilling through including individual sections of the inductor, which enhances the quality of the moulds and goods due to the lower quantity of the oxide inclusions. The oven consists of a working chamber (1) with a fire-proof lining (3). The lower part is plated by a metallic conductor (5), forked into two branches - lower (6) and upper (7), located at a blunt angle alpha one against the other. The external side of the working chamber (1), an inductor is placed (9), which consists of two autonomous sections (10 and 11), located respectively below the branches (6 and 7) of the metallic conductor.

Title: Method for preparing of modified paa- gel
Inventor: NAJDENOV KIRIL L
IPC: G01N27/26
Filed: 1989-10-30
Abstract: The modified PAA gel is used in analysis of biological subjects containing amphoteric macromolecules. This method is based on the principle of isoelectric focusing, which is used to perform highly efficient separation of an albumin mixture containing components with similar isoelectric points for qualitative and quantitative analysis. The polyacrylamide gel is obtained by mixing acrylamide, N,N-methylenebisacrylamide, and catalytic quantities of N,N, N',N'-tetramethylethylenediamine and ammonium persulphate. The gel is processed with hydrazine until a hydrazine derivative is obtained, after which it is treated with NaN1O2 in a hydrochloric acid environment at temperature 0 degree C while adding polyamine; the reaction runs during 3-5 hours at 0 degree C. The resulting polyamine-modified polyacrylamide gel is stored in 0.1 mole/L NaCl solution in a fridge.

Title: Cable transport system with garaging of carriers
Inventor: MEINDL BERND
IPC: B61B11/00
Filed: 1989-11-17
Abstract: A cable conveyance having a storage region for garaging the carriers which can be decoupled from the transport cable.  The carriers are displaced along a transport rail to the storage regions by a reversible drive and are permitted to move by gravity along storage rails into this region or by positively tilting these storage rails back to the transport rail to return to the cable.       Thus within the storage region the displacement of the carriers is by gravity only and there is no need to provide a special drive for entrainment of the carriers along the storage rails.

Inventor: HOSOYA NOBUKAZU
IPC: H03B5/36
Filed: 1990-04-19
Abstract: An active filter circuit includes a first and second differential pairs each having a pair of transistors. A capacitor is connected to a collector of each on transistor of the first and second differential pairs. A first and second negative feed-back paths are connected, respectively, between the collector and a base of one transistor of the first differential pair and between the collector of one transistor of the second differential pair and a base of the other transistor of the first differential pair. By applying suitable voltages to respective inputs of the differential pairs, the active filter circuit functions as a band-pass filter, lowpass filter, high-pass filter, band elimination filter or phase-shifting filter with the same circuit configuration. A current mirror circuit correlatively changes current amounts of the first and second differential pairs in response to a control voltage, whereby a filter characteristic can be changed.

IPC: H01M10/05
Filed: 1990-05-25
Abstract: NON-AQUEOUS ALKALI BATTERY HAVING AN IMPROVED CATHODE Abstract This invention relates to a process of fabricating a rechargeable non-aqueous cell and to a cell produced by the process. The cell includes a unique laminated cathode structure. Other structural features of the non-aqueous cell including anode, non-aqueous electrolyte and separator, are generally conventional. The novel cathode is composed of a current collector consisting of an unperforated metal foil to which are bonded mats of cathode active material, selected from transition-metal chalcogenides. In the process of forming the cathode, a non-perforated metal foil, such as aluminum, is coated with a layer of bonding polymer and after the mats of cathode-active material, such as niobium triselenide, are placed on both sides of the metal foil, the composite is compacted, preferably by passing between rollers. Electronic conduction is enhanced by either admixing carbon black with the polymer or coating that surface of the mats which is to be in contact with the metal foil, with a thin layer of carbon black. This design results in cells which show a distinct improvement in energy at higher rate discharges, e.g. at 3-4A, or at lower temperatures, e.g. -20°C, lower cost and weight than cells with conventional cathode collector having screen or grid of expanded metal, e.g. Ni, and are expected to ameliorate internal shorts resulting from the use of ex-met grids.
